Summary

Ketorolac can lessen the blood pressure control from valsartan and hydrochlorothiazide, and the three drugs together carry a notable risk of acute kidney injury and hyperkalemia. Risk is higher in older, dehydrated or renally impaired patients.

What this interaction means in plain words

Hydrochlorothiazide-valsartan and Ketorolac can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Hydrochlorothiazide-valsartan belongs to Cardiovascular; Ketorolac belongs to Musculoskeletal.

Evidence level: High

Why it happens

NSAID inhibition of renal prostaglandin synthesis reduces renal perfusion and sodium excretion, compounding angiotensin receptor blockade and diuretic-induced volume loss.

What to do

Avoid combination where possible and limit ketorolac to the shortest course, ensuring adequate hydration. Monitor creatinine, potassium and blood pressure during use.

What to ask your pharmacist

  • Does the benefit of taking both outweigh the risk in my case?
